DipWSET D4: Sparkling wines Flashcards
Refer to sparkling wine styles produced in Chile
- Most wines are made by the tank method (90%)
and are made to be fruity (Brut and slightly sweeter) - Principal grape varieties: Chardonnay, Pinot Noir and Sauvignon Blanc
- Method traditional varieties: Chardonnay and Pinot Noir. País (Blanc de Noirs or Rosé) and Moscatel.
Refer to the different types of companies engaged in the production of sparkling wine in USA
- Specialist sparkling wine companies often founded by Champagne and Cava houses. Distribute across the USA and export small quantities, e.g. Roederer Estate
- Wine companies that produce small batch, premium sparkling wine. These wines are sold at the cellar door, direct-to-consumer, at the winery’s restaurant or locally, e.g. Schramsberg
- Large wine companies that produce inexpensive sparkling wines as part of a larger range, including companies with national and international distribution, e.g. Barefoot and Cupcake
Where are the grapes for sparkling wine generally grown in Chile?
For premium sparkling wines, fruit is generally grown in areas where there are cooling influences, such as:
- Coastal areas (Casablanca, San Antonio, Limarí)
- Andean foothills
- Milder regions in the south (Bío-Bío)
Fruit for inexpensive wines is sourced from the warm Central Valley
Refer to Washington in terms of sparkling wine production
- This is the second largest producer of sparkling wine in USA
- Northerly latitude and high diurnal range
- Blends of Chardonnay, Pinot Noir and Meunier
- Blanc de Noirs and Blanc de Blancs
- Single varietal wines made from other varieties (Muller-Thurgau, Riesling, Gewurztraminer) are made.
Refer to Oregon in terms of sparkling wine production
- Oregon has increased added sparkling wine to its Pinot Noir and Chardonnay offer
- Suitable cool climate of Willamette Valley
- Argyle is the pioneer and larger specialist producer
- Radiant Sparkling Wine (Specialist company)
Refer to the most important areas for sparkling wine production in California
Anderson Valley (Mendocino County)
- Northwest of this AVA is close to the Pacific Ocean. Cool breezes and fog are conveyed along the Navarro River valley to moderate temperatures and reduce sunshine hours
- Home to Roederer Estate
- Producers making still wine also make small amounts of sparkling wine.
- Producers from outside the region buy fruit form here for sparkling wine.
Russian River (Sonoma County)
- Cool breezes and fog provide cooling influences via the river and through the Petaluma Gap
- Home to Korbel
Carneros (Sonoma and Napa counties)
- Significant cooling influences from San Pablo Bay
- Home to Gloria Ferrer (Freixenet) and Domaine Carneros (Taittinger)
What is the purpose of blending in sparkling wines?
- Balance
- Consistency
- Style
- Rosé wines
- Complexity
- Minimisation of flauts
- Volume
- Price
What are the factors within the grape variety that can influence the style of the sparkling wine?
- Intensity of aromas (aromatic versus neutral variety)
- Ability to retain acidity when ripening
- How the base wine responds to autolysis (when applicable)
Refer to Blanc de Blanc and Blanc de Noirs sparkling wines from an ageing perspective
- Blanc de Blancs can be leaner and more austere in youth, but often have unmatched ageing potential
- Blanc de Noirs are generally thought to age more rapidly than Blanc de Blancs
List the EU labeling terms for sweetness in sparkling wines
- Brut Nature: 0-3 g/L
- Extra Brut: 0-6 g/L
- Brut: 6-12 g/L
- Extra-Sec/Extra-Dry: 12-17 g/L
- Sec/Seco/Dry: 17-32 g/L
- Demi-Sec/Semi Seco/Medium Dry: 32-50 g/L
- Dulce/Sweet: 50+ g/L
Refer to Vallée de la Marne
- Major plantings are Meunier (72%) on clay, marl and sandy soils, producing fruity wines
- Frost prone valley, Meunier adapts well
- Chardonnay is grown (clay) and used in early drinking styles
- Grand Cru village of Aÿ is located here
List the grape varieties used for sparkling wine in Argentina
- Inexpensive sparkling wine is typically made by Carbonation. Most commonly made of Pedro Giménez, Chenin Blanc and Semillon
- Tank method: A range of varieties, including Chardonnay and Pinot Noir
- Traditional method: Pinot Noir and Chardonnay
Describe the two main categories of sparkling wine in South Africa
- Inexpensive, carbonated sparkling wine, often sweet (off-dry to sweet), consumed in the domestic market and exported to the sub-Saharan territories. Grape varieties: Sauvignon Blanc, Muscat, Pinotage
- Cap Classique, traditional method sparkling wine, principally made of Chardonnay, Pinot Noir, Chenin Blanc and Pinotage. Standards include: i) 2nd fermentation in same bottle that goes to the market, ii) min. 3 bar pressure post-disgorgement, iii) min 12 months on lees
What caused the big boost in the decade after 2005 in the sparkling wine industry in Argentina?
The sparkling wine sector was given a big boost in the decade after 2005 resulting from an agreement between the government and the national wine trade body to remove a domestic tax of 12% on sales in return for investment in sparkling wine by the industry
Where are grapes for sparkling wine sourced in South Africa?
- Fruit is grown and sourced from a wide range of regions, principally Robertson, Stellenbosch, Paarl, Darling and Tulbagh
- Only Robertson and Bonnievale have significant amounts of limestone soils, which some believe produces higher quality wine. These are narrow valleys where temperatures drop in the afternoon because of the cool breezes from the ocean at Cape Agulhas that run up the Breede River.
Refer to winemaking practices for Cap Classique
- Quality-minded growers will hand harvest and whole bunch press
- Better producers will separate press fractions and use them as needed during blending
- Acifidication of must is common place
- Some producers ferment a portion of the fruit in old barrels for more textural richness in premium wines
- Malolactic conversion is decision of the producer
- Reserve wines (≈ 10%) are used by premium houses to add depth of flavour and ensure consistency
- Min. 12 months on lees. Some producers will do 15-18 months for NV and higher for prestige cuvées.
- Rosé: Blending or maceration (less common)
What are the advantages of Marlborough for the production of sparkling wine?
Advantages include:
- Low risk of late frost or hailstorms
- Prevalent northwest wind helps to remove air moisture quickly after rain, reducing the threat of fungal diseases
- Harvest two weeks before still wines minimises risks posed by autumn rain and the tail end of tropical cyclones
Refer to grape growing regions for sparkling wine in Australia
- Grapes for traditional method sparkling wine are grown in the cooler regions: Tasmania, Yarra Valley, Adelaide Hills, and Alpine regions of VIC and NSW
- For inexpensive sparkling wine: Riverland, Riverina, and Murray-Darling
- For red sparkling wine (Shiraz): Central VIC, Barossa Valley and McLaren Vale.
- Australian Prosecco: King Valley
Refer to traditional method practices in New Zealand
- Quality conscious producers will hand harvest and whole bunch press
- Most carry out 1st fermentation in stainless steel tanks
